 * @brief Returns an HTTP query parameter.
 * Query parameters are key-value pairs that are appended to the URI after a question mark.
 * The name parameter specifies the name of the query parameter to retrieve. If it is set,
 * the value is written to the value parameter and true is returned. If the parameter does
 * not exist, value is left unchanged and false is returned. If the parameter is used
 * without a value, an empty string is written to value and true is returned.
 * @param name The name of the parameter to retrieve. If the parameter exists multiple times,
 * the first occurence is used for the value. Use beginQueryParameters() to retrieve all values.
 * @param value The target to write the value to, if the parameter exists.
 * @return true iff the parameter exists and the corresponding value has been written.

 * @brief Provides iterator access to the query parameters
 * Query parameters are key-value pairs that are appended to the URI after a question mark.
 * If you want just a specific parameter, have a look at getQueryParameter()
 * The iterator will yield pairs of std::string, of which the first value specifies the
 * query parameter key and the second value corresponds to the query parameters value.
 * If the entry is value-less, the second value will be the empty string.
 * If the same key is used multiple times in the query, the iterator will yield it multiple
 * times, once for each occurence with the specific value.

 * @brief Checks for the existence of a path parameter and returns it as string.
 * Path parameters are defined by an asterisk as placeholder when specifying the path of
 * the ResourceNode and addressed by an index starting at 0 for the first parameter.
 * For values of idx that have no matching placeholder, value is left unchanged and the
 * method will return false.
 * @param idx Defines the index of the parameter to return, starting with 0.
 * @param value The value is written into this parameter.
 * @return true iff the value could be written.

 * to assure that the index exists. Otherwise, an empty string will be returned.
